The purpose of this report was to evaluate the efficacy of cardiomyotomy combined with fundoplication in the treatment of achalasia. Results obtained in 15 patients are compared with those collected in 19 asymptomatic patients treated by the classical Heller operation (12 patients), or by cardiomyotomy combined with suture of phrenoesophageal ligament to the underside of the diaphragm (7 patients). The preventive action of fundoplication on reflux esophagitis and especially the effect of surgery on esophageal emptying are particularly examined, using two rigorous isotopic tests. It is demonstrated that even asymptomatic patients have, after cardiomyotomy without antireflux maneuvers, a very high risk of esophagitis. The statistical comparison using the gastroesophageal reflux index between patients treated by Heller cardiomyotomy and normals wasp <0.001 to the classical Heller, and 0.01

0.1), and maintained the improvement of the esophageal emptying.
